I completed the survey as well. I was very disappointed in the questions asked and the lack of associated follow up questions. I think Nokia needs to hire a new company to do their surveys. Here is what I wrote in the final comments:

Many of the questions in this survey seemed ill conceived, poorly targeted and didn't result in follow up questions. For instance, if you are going to ask how often someone checks email with the 770, you might follow up with a question regarding the quality of the email client. In my case, until recently, I did not use the 770 for email at all, due to the utter inadequacy of the built in email client. I only recently started using the 770 for email due to the release of a port of the full Sylpheed email client. The question regarding the 5 way rocker was particularly onerous in my mind, in this regard. I don't use the rocker as much as I would like, due to it being too small with not enough mechanical feedback. I am afraid responses to this question could lead to the elimination of the rocker in future IT designs, where I would actually like more emphasis on this area, in particular the improvement of the rocker and inclusion of several non-function specific buttons on the right side and/or top right edge. As someone with a reasonably rigorous knowledge of statistics, I feel the numeric data conveyed by this survey will be very inaccurate in giving Nokia a real sense of how people actually use the 770 and in determining how to direct development of future Internet Tablet designs.
